FLOUR-BOLT.

SPECIFICATION forming part of Letters Patent No. 342,146, dated May18,1886.

Application filed January 13, 1886, Serial No. 188,390.

To aZZ whom, it may concern.-

Be it known that I, ODEON-H. TiTUs, a citizen of the United States, anda resident of Wilmington, in the county of New Castle and State ofDelaware, have invented certain new and useful Improvements inFlour-Bolts; and I do hereby'declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in whicl1 Figure l is a side view of my improvedmachine for purifying flour during the process of.

manufacture. Fig. 2 is a plan view of the same; and Fig. 3 is a verticalsectional view on line 00, Fig. 2.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to machines for purifying flour during theprocess of manufacture; and it consistsin the improved construction andcombination of parts, hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the casing of thescalper 0r bolting-reel B, which is provided with beaters O, of theusual construction, and which casing is provided with the usualconveyor, D, at its bottom. A casing, E, is secured upon the top of thereel-casing, and this casing or box E is provided with a line, F,projecting rearward,

which flue enters the casing of a fan-blower, G, having adischarge-flue, H, at .its upper side. The front side of the box uponthe reelcasingwhich box I sh all term the air-chamber-has verticalchutes I, which enter with their lower ends into the upper forwardcorner of the reel-casing, and which communicate with the air-chamberthrough apertures J, provided with slides K, by means of which slidesthe apertures may be more or lesscovered, as desired. The rear side ofthe casing is provided with one or more downwardly-inclined slots, L, atabout the middle of the reel, and the reel revolves in the directionindie cated by the arrow in the drawings, having its upper portiontraveling away from the upper forward corner having the chutes.

The fan, which draws the air from the air- (No model.)

chamber, and consequently from the reel-cas ing when the apertures areopened, creates a mild air-current from the downwardly-inclined slot orslots in the rear side of the reel-casing, under the reel, and upthrough the chutes, and through the air-chamber and fan, and the reel,revolving in the same direction as the air-current, will force allimpurities, cellulose, hair, and other foreign matter toward the upperfront corner, whence they will be drawn out of the casing by theair-curreut into suitable receptacles. I having found by experience thatall these impurities, which are lighter than the flour-stock, withoutregard to the fineness of the said stock, will always seek the uppercorner, toward which the heaters revolve from the lower half of theirrex olution, while the good stock will seek the bottom of thereel'casing and be carried 01f by the conveyer, and for this reason Iplace the airchutes entering at that corner of the casing and draw alight current of air through them around the under side of the reel,which current is not strong enough to carry off any of the good stock,while it will carry off all the impurities, which, generally, are firstremoved during a later stage of the process of manufacturing the flour.

It will be seen that the incline of the slot or slots in the rear sideof the reelcasing will give the air-current a downward direction, andthe current of air may be regulated by the slides covering the aperturesof the air-chutes, the opening or closing of the said aperturesincreasing or decreasing the strength of the air-current. The airchamberwill also act as a trap for any particles of good stock which might becarried off with the impurities by a too heavy current of air, theheavier particles of good stock falling toward the bottom of the casingduring their passage through the same, while the impurities, which arelighter, will pass on through the casing and fan, and the stockaccumulated in the bottom of the airchamber may be removed throughsuitable doors, M, in the sides of the chamber, and be subjected tofurther treatment with other flourstock.

I am aware that it is not new to supply the casing of bolting-reels withmeans for removing the dust and impurities out of flour durverticalpartition having an opening near its upper portion, an adjusting-slidefitting over said opening, and a suction-fan connected With [5 saidair-chamber, as shown and described.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
